All State Department officials are required to sign the “separation statement” when they leave the department, known as the OF-109 form. However, Abedin has a private email address (huma@clintonemail.com) on the same private server that Clinton does, and when she leaves the department in February 2013 she does not turn over any of her emails from it, including work-related emails.

Her emails will not be handed over until a couple of years later, after various lawsuits and investigations. In signing the form, Abedin acknowledges she could be subject to “criminal penalties” for lying on the document.
